Negative two B subtracted by C plus four B plus three C

Marianna [84]

Answer:

First we should make this word problem into an equation.

. * (_poof_) *,

-2b - c + 4b + 3c There we go. . . much better.

Now we can simplify the equation by combining like terms.

( - 2b + 4b ) + ( - c + 3c ) = ( 2b ) + ( 2c )

So the simplified form of this would be 2b + 2c.

Line GH contains points G(–2, 6) and H(5, –3). What is the slope of ?

Anon25 [30]

Answer:

$\Huge\boxed{\mathsf{-\frac{9}{7} }}}$

Step-by-step explanation:

SLOPE FORMULA:

$\displaystyle \mathsf{\frac{Y_2-Y_1}{X_2-X_1}=\frac{RISE}{RUN} }$

Y2=(-3)

Y1=6

X2=5

X1=(-2)

Solve.

$\displaystyle \mathsf{\frac{(-3)-6}{5-(-2)}=\frac{(-3)-6}{5+2}= \frac{-9}{7}=\boxed{\mathsf{-\frac{9}{7}} }}$

The slope is -9/7.

4. A sports car accelerates from rest to a final velocity of 64 m/s at a rate of 12.3

Ivanshal [37]

Answer:

$t = 5.2\ s$

Step-by-step explanation:

Given

$a= 12.3m/s^2$ --- acceleration

$v = 64m/s$ --- final velocity

$u =0m/s$ --- initial velocity (it is 0, because the car starts from rest)

Required

Determine the time taken

This will be solved using Newton's first equation of motion:

$v = u + at$

Substitute values for v, u and a

$64 = 0 + 12.3*t$

$64 = 12.3t$

$12.3t = 64$

Make t the subject

$t = \frac{64}{12.3}$

$t = 5.2\ s$

Hence, the time taken is approximately 5.2 seconds
